The examples listed throughout this book assume you are using Release 2.

Many of the libraries and functions documented in this manual are
available in all versions of the Amiga operating system.  Others are
completely new and cannot be used unless you have successfully opened the
appropriate version of the library.

To find out which functions are new with Release 2 refer to the ROM Kernel
Reference Manual: includes and autodocs.  the functions which are new are
marked with (V36) or (V37) in the NAME line of the function Autodoc.
These new functions require you to use a matching version number (36, 37,
or higher) when opening the library.

exit gracefully and informatively if the required library version is not
available.
